  Embodiments described herein relate generally to a plant monitoring apparatus and a program for monitoring an alarm generated in a plant.

  The plant monitoring device displays an alarm of the equipment on the alarm list screen when the data related to the equipment arranged in the plant exceeds the upper limit value or the lower limit value, or when a failure occurs in the equipment.

  On the alarm list screen, newly generated alarms are displayed at the top and old alarms are displayed at the bottom. When a new alarm occurs after an unrecovered alarm (currently occurring alarm), the newly generated alarm is displayed at the top of the screen, and the old unrecovered alarm is sent from the alarm list screen and disappears There is. If the unreturned alarm is not displayed on the alarm list screen, it becomes difficult for the user (monitor) to check the unrecovered alarm even if the alarm event needs to be repaired.

  The alarm list screen displays both alarms that have been recovered and alarms that have not yet been recovered, that is, alarm history. Among plant monitoring devices, there is a device that displays an alarm summary screen for selecting and displaying only data related to unreturned alarms from display contents of an alarm list screen. In the conventional plant monitoring apparatus, the alarm summary screen is displayed when the user issues an instruction to display the alarm summary screen. For this reason, if the user does not instruct the display of the alarm summary screen, the alarm summary screen is not displayed, and the response to the alarm may be delayed. If the response to the alarm is delayed, the equipment will fail or become uncontrollable, making it difficult to operate the plant properly. In addition, it may be difficult to collect accurate data regarding equipment.

(First embodiment)
In the present embodiment, a description will be given of a plant monitoring apparatus that displays an alarm state data attached to an alarmed device on the plant monitoring screen when an alarm is generated for the device installed in the plant. .

  The plant monitoring apparatus according to the present embodiment displays the status data of the alarm that is occurring conspicuously as time elapses.

  FIG. 1 is a block diagram illustrating an example of a configuration of a plant monitoring system according to the present embodiment.

  The plant monitoring system 1 includes various devices 21 to 2n and a plant monitoring device 3. In this embodiment, the plant monitoring system 1 monitors a water plant (monitoring target plant) including at least one of a waterworks plant and a sewerage plant.

  The devices 21 to 2n are installed in the roadside station of the water plant. The devices 21 to 2n are, for example, water distribution equipment, flow meters, water pressure meters, turbidity meters, residual salt meters, water temperature meters, telemeters, UPSs, chlorine meters, and the like. The devices 21 to 2n transmit the measurement values to the plant monitoring device 3 via the network 4.

  The plant monitoring device 3 includes a communication unit 5, an input device 6, a display device 7, a processor 8, and a storage device 9.

  The communication unit 5 receives measurement values via the network 4 from the devices 21 to 2n.

  The input device 6 receives various instructions for the plant monitoring device 3 from a user such as a monitor.

  The display device 7 displays various data held in the plant monitoring device 3 according to the instruction received by the input device 6.

  The processor 8 executes the monitoring program P1 stored in the storage device 9. Thereby, the processor 8 executes processing as the measurement value acquisition unit 81, the threshold setting unit 82, the alarm registration unit 83, the summary generation unit 84, the level setting unit 85, the generation unit 86, and the display control unit 87.

  The measurement value acquisition unit 81 acquires the measurement values of the devices 21 to 2n received by the communication unit 5 and stores the measurement value data D1 including the measurement values of the devices in the storage device 9.

  The threshold value setting unit 82 stores threshold data D2 including threshold values for alarm determination for the devices 21 to 2n set by the user who operates the input device 6 in the storage device 9.

  As in this embodiment, the threshold data D2 can be set and changed, so that the number of alarms can be adjusted flexibly. For example, the number of alarms can be increased by tightening the alarms (narrowing the allowable range determined based on the threshold). In addition, for example, the number of alarms can be reduced by loosening the alarms (widening the allowable range determined based on the threshold value).

  The plant monitoring screen data D3 stored in the storage device 9 includes device identification data D31 of the devices 21 to 2n and display position data D32 of the devices 21 to 2n. The plant monitoring screen data D3 arranges the devices 21 to 2n indicated by the device identification data D31 at the positions indicated by the display position data D32, and visually represents the connection relationship between the devices 21 to 2n.

  The alarm registration unit 83 is based on the measured value data D1 and threshold value data D2 stored in the storage device 9, and the measured values of the devices 21 to 2n are based on threshold values (upper limit value or lower limit value). Judge whether or not it exceeds the allowable range. The alarm registration unit 83 determines that an alarm has occurred for the device when the measured value of the device exceeds the allowable range. And the alarm registration part 83 is the apparatus identification data D41 of the apparatus which issued the alarm (the apparatus corresponding to the measured value exceeding the allowable range), for example, during the occurrence of an abnormality, the content of the alarm, the importance of the alarm (for example, a minor failure or State data D42 including the major failure) and alarm occurrence time data D43 are associated with each other and registered in the alarm list data D4. The contents and importance of the alarm are associated with, for example, a threshold value, and when the measured value exceeds the threshold value, the contents and importance of the associated alarm are incorporated into the state data. It is good.

  Further, the alarm registration unit 83 determines that the device is restored when the measured value of the device in which the alarm has occurred falls within the allowable range. Then, the alarm registration unit 83 registers the device identification data of the restored device (the device corresponding to the measurement value within the allowable range), the status data indicating the restoration, and the restoration time data in the alarm list data D4.

  As described above, the alarm list data D4 is data for managing the history of alarm generation, alarm recovery, and the like of the devices 21 to 2n.

  The summary generation unit 84 selects, from the alarm list data D4 stored in the storage device 9, device identification data D51 for the currently occurring alarm, for example, status data D52 including alarm contents and alarm importance, The generation time data D53 is selected. Then, the summary generation unit 84 associates the selected device identification data D51, status data D52, alarm generation time data D53, and elapsed time data D54 indicating the time that has elapsed since the alarm occurred, and registers them in the alarm summary data D5. To do.

  As described above, the alarm summary data D5 is data relating only to an alarm in which an alarm is generated.

  When the alarm is recovered, the summary generation unit 84 deletes the device identification data, status data, alarm occurrence time data, and elapsed time data corresponding to the recovery from the alarm summary data D5, thereby deleting the alarm summary data D5. Data related to the alarm that has been recovered from may be excluded. As a result, the alarm summary data D5 becomes data obtained by extracting only the data in which the alarm is generated from the alarm list data D4.

  Based on the alarm list data D4 or the alarm summary data D5 stored in the storage device 9, the level setting unit 85 determines whether or not a predetermined period has elapsed since the alarm was generated for the alarm-generating device. Then, the level setting unit 85 sets the alerting level higher as the elapsed time is longer for the alarm that has passed for a predetermined period from the occurrence. In the present embodiment, an alarm with a higher alert level is displayed in a conspicuous display mode.

  The generation unit 86 includes plant monitoring screen data D3 stored in the storage device 9, alarm list data D4 or alarm summary data D5 stored in the storage device 9, and an alarm generating device set by the level setting unit 85. Based on the alert level, the device identification data D31, D41, or D51, the state data D42 or D52 of the display mode corresponding to the alert level, and the alarm are generated for the device in which the alarm is generated in the plant monitoring screen data D3 The plant monitoring screen data D6 with an alarm in which the time data D43 or D53 and the elapsed time data D54 are associated is generated. And the production | generation part 86 memorize | stores the generated plant monitoring screen data D6 with a warning in the memory | storage device 9. FIG.

  In the present embodiment, the plant monitoring screen data D3, the alarm list data D4, and the alarm summary data D5 include device identification data D31, D41, and D51, respectively, and are associated with each other. Therefore, generation of alarmed plant monitoring screen data D6 is possible by incorporating relevant data in other data.
